Abstract
An exhaust muffler for a marine engine comprises a first vertically oriented tubular member having a lower end sealingly extended through the bottom of a main body chamber and an upper end extending upwardly through the top of the chamber. A second tubular member surrounds and is spaced from the first tubular member for forming a passage therebetween, and has its upper end sealingly extended through the top of the chamber and its lower end extending to a point below two chamber inlets, yet spaced from the bottom of the chamber. A cap seals the upper end of the second tubular member to invert upwardly flowing exhaust gases and cooling fluid within the passage between the first and second tubular members downwardly into the first tubular member for discharge from the muffler.
